From the article: Monsanto knows that consumers won't voluntarily buy their products - a lesson learned in Europe when GE foods there were required to be labelled as such. In America, the company and its allies have spend millions to defeat local labelling initiatives, most recently in California. But if the company successfully crowds out conventional farmers, Americans won't have a choice - with or without a label."

From the article: But there is an unpalatable truth to face for those of us with a bag of quinoa in the larder. The appetite of countries such as ours for this grain has pushed up prices to such an extend that poorer people in Peru and Bolivia, for whom it was once a nourishing staple food, can no longer afford to eat it...In Lima, quinoa now costs more than chicken. Outside the cities, and fuelled by overseas demand, the pressure is on to turn land that once produced a portfolio of diverse crops into quinoa monoculture. (my emphasis added)
